This was a lush garden in the middle of the park that oddly enough was fenced off, and an admission fee was being charged to enter (even more than the entry fee for the park itself). Unfortunately, there was nobody selling or taking tickets, so I found a way past the fence to get closer to the hoopoe pictured below (and got caught by some worker, who luckily said it was OK). Maybe I was the one who caused its crest to shoot up in alarm!
